Answer:
(a) 
(b) 
(c) Maximum area
square meters
Step-by-step explanation:
(a)
Given:
Total length for fencing = 160 m
Width of the rectangle =
m.
Let the other length of the rectangle be
m.
Then, from the figure,

Now, area of a rectangle is equal to the product of its length and width.
So, area is, 
(b)
Given:

For maximum area, derivative of area with respect to
must be 0.
So, 
Therefore, for maximum area,
.
(c)
Given:

Maximum area occurs at
. Plug in 40 for
in
expression. This gives,
Maximum area is,

Therefore, maximum area is 3200 square meters.
Answer:
Speed and velocity are both measured using the same units. The SI unit of distance and displacement is the meter. The SI unit of time is the second. The SI unit of speed and velocity is the ratio of two — the meter per second. I hope that this is useful information.
Step-by-step explanation:
If you mean trying to figure out what “y” is without the 4. first you have to get the 4y by itself. To do that, subtract 8x from the left side and subtract it from the right side.
-4y=20-8x
Then subtract everything by -4
y=-5+2x
I believe that is the answer (bolded part)
Answer:
n=12
Step-by-step explanation:
n can be multiple answers, but I'm pretty sure if you multiply 6*2 you will get 12. Since you want to do with distributive property.
12+6/2=9
Answer:
X = -1/3, 1/3
Step-by-step explanation:
6x^2 - x = 1
(subtract 1 from both sides)
6x^2 - x - 1 = 0
(factor)
(6x - 3) (6x + 2)
(simplify)
(2x - 1) (3x + 1)
(Solve for x in each parentheses)
2x-1= 0 and 3x+1=0
X= -1/2 X= -1/3
